3. Bu- : Used in the past participle (bu) and past simple.

Tu bois /bwa/ You drink (informal)
Il / Elle / On boit /bwa/ He / She / One drinks

The imperfect describes habitual actions or continuous past events. Take the nous present stem (buv-) and add regular imperfect endings (-ais, -ais, -ait, -ions, -iez, -aient):

  • Je buvais
  • Tu buvais
  • Il / Elle / On buvait
  • Nous buvions

  • Je bus
  • Tu bus
  • Il / Elle but
  • Nous bûmes

  • Que je boive
  • Que tu boives
  • Qu'il / elle / on boive
  • Que nous buvions
